My toddler is like this he has very specific things he will eat and is uninterested in anything else. Though recently he has begun slowly trying some new things. Yesterday we had a play date and the kids were eating Mac and cheese my LO has never been interested but in Mac and cheese but Yesterday he actually tried some I was so proud of him. I have noticed if I dramatize going mmmmmmm yummy he gets interested 😅
Mine will not almost anything at home, but at daycare, she needs anything and everything
I definitely think that's an age thing.
